The commission asked the county for more information and to answer several key questions about its plans to leave a rock revetment in place to help slow erosion of the park and green space.

The letter asked for several pieces of information, including two sets of detailed cross sections of the revetment that show the project footprint in relation to bordering properties.

The commission also asked for a description of the rock to be retained as well as reports that look at “wave modeling, geomorphic interpretation, wave run-up,” and a coastal flooding and erosion vulnerability assessment.

The debate centers on the future of the park, the county's most popular beach destination.

Some environmentalists have called for the removal of the rocks to allow for the beach to return to its natural state. They would like the removal of 1,200 feet of rocks, some as large as 8 feet tall and 15 feet wide, buried under the sand, yanked from the beach.

The rocks were installed as an emergency measure a decade ago to prevent the park from major storm damage. During large storm events, the high tide rushes up on the grass, and over the years has slowly eroded the size of the park, which is popular among families and children.

The EIR for the project says that about 2.6 acres, or about 60 percent of the park, would be eventually lost if the rock revetments are removed.

The rocks, however, are now unpermitted. Opponents of the rocks argue that the artificial barriers contribute to the loss of sand, and that over time, the beach will disappear.

The county Board of Supervisors in March voted to leave the rocks and sent a "no-project" alternative to the Coastal Commission.

The commission responded in June with questions. It's up to the county now to answer those questions.

Bennett and others at the meeting said they expect that the commission will ultimately back the county's plans. They cited a recent decision by the commission to allow revetments in other parts of California.

Farr said he expects everything to work out in the end for the supporters of the park.

"Goleta Beach Park is for the people of the Goleta Valley," Farr said. "It's the best opportunity for the people of the Goleta Valley to interact with the ocean. It's a prime point for us to experience nature and the ocean. It is what everyone in the Goleta Valley wants."
